Question 2239: How do you solve polynomial equations such as:
(x-3)(x-squaured+3x-4)=0
(x+2)(x-squared+5x+1)=0
Answer by matthew_sessoms(39) (Show Source): You can put this solution on YOUR website!
Factor out the second equation that's in parentheses...
(x+4)(x-1)
Now we get the 3 factors...
(x-3)(x+4)(x-1)=0
Now solve for x in each parentheses, and we get..
x=3, x=-4, x=1
{3, -4, 1)
The second equation cannot be factored and therefore, must be solved using the quadratic formula, which is
Plug the values in, like this
Which simplifies to...
So the answer to the second problem you gave is...
{-2,,}
Hope this helps!
